摘要:
An optical element includes a light-transmitting structure and a first reflection-prevention layer. The light-transmitting structure has a first surface and a second surface facing the first surface. The first reflection-prevention layer includes a plurality of first light-refractive index buffering particles deposited on the first surface such as the concentration of the particles decreases as the distance from the first surface increases. The first reflection-prevention layer decreases the variation of a light-refractive index from the light-transmitting structure to an air layer to decrease the light reflectance of the first surface. Therefore, the light transmittance of the light-transmitting structure is increased due to the reflection-prevention layer formed on a surface of the light-transmitting structure, so that luminance may be enhanced. Moreover, the reflection-prevention layer may enhance the resistance of the light-transmitting structure to external impacts.

A fluorescent lamp includes a lamp body, a fluorescent layer and a discharge electrode. The lamp body has a discharge space in which ultraviolet light is generated. The fluorescent layer is formed on an inner surface of the lamp body to change the ultraviolet light into visible light. The discharge electrode is on an end portion of the lamp body to apply a voltage to the discharge space. A ratio of intensities of the visible light at wavelengths of about 545 nm and about 516 nm is about 1.32:1 to about 1.71:1. Therefore, color reproducibility and luminance may be improved.

A display device includes a display panel and a light emitting device to supply light to the display panel. The light emitting device includes a light emitting element emitting a first light and a fluorescent layer receiving the first light, transmitting a portion of the first light, converting a remaining portion of the first light to a second light having a wavelength range different from the first light, and emitting the second light. The second light emitted by the fluorescent layer has a full width at half maximum equal to or larger than 110 nanometers (nm) and a light emission spectrum having a peak wavelength within a wavelength range of about 530 nm to about 560 nm. The second light has a light emission intensity corresponding to 10 to 30 percent of a peak light emission intensity of the first light.

A lamp and a display device including the lamp, in which the lamp includes a discharge tube, a discharge gas, a blue fluorescent substance, a green fluorescent substance and a red fluorescent substance. The discharge gas is disposed in the discharge tube. The blue, green and red fluorescent substances are disposed at an inner wall surface of the discharge tube to generate a blue light, a green light and a red light by ultraviolet rays emitted by the discharge gas. The red fluorescent substance includes at least two different red fluorescent substances, which generate the red light having peak wavelengths different from each other. Thus, the color reproducibility may be improved using the two different red fluorescent substances.
